RAIL-CHAIR FOR GlRDER RAlLS.

SPECIFICATION forming part of Letters Patent No. 388,097, dated August21, 1888.

Application filed February 15, 1888. Serial No. 264,123.

To all whom it may concern.-

Be it known that I, ROBERT WV. WELOH, of Johnstown,in the county ofGambria and State of Pennsylvania, have invented a new and usefulRail-Chair for Girder-Rails, which invention is fully set forth andillustrated in the following specification and accompanying drawings.

The object of this invention is to provide a two-part chair which shallbe strong, light, and cheap.

The invention will first be described in detail, and then particularlyset forth in the claims.

In the accompanying drawings, Figure 1 illustrates the chair in endelevation, showing the rail secured thereto in cross-section. Fig. 2shows the right half of the chair detached, in side elevation,lookingfrom the right. Figs. 3 and 4 show, respectively, the two halves of thechair in perspective. Fig.5isa view similar to that of Fig, 1, showing amodified form of chair having a center bearing-rail (shown in cross 7section) mounted thereon. Fig. 6 shows in side elevation the right halfof the chair shown in Fig. 5, looking from the right, detached.

in said figures the several parts are indidicated by letters ofreference, as follows:

The letterA indicates one half or part of the chair; B, the other partof the chair; 0, the rail mounted on the chair; and D, the bolt which,through holes d, clamps the two parts of the chair together with asplice-bar fit to the rail through its web, the flanges of the railresting on the lugs L as bearings. One of said lugs is formed on eachpart of the chair. Said lugs are cut out of the metal itself, as shownin the several figures, by suitably bending the lug, its location beingfixed by the cutting of its exterior lines through the metal.

In Figs. 1, 2, 3, and 4 each half of the chair (No model.)

is first rolled as a blank like a T-plate, with one flange somewhatwider than the other, if preferred, as shown in said figures. The blank5 can then be given its necessary shape or form by drop-forging orotherwise, as may be preferred.

In Figs. 5 and 6 each half as a blank may be formed from a flat platesheared or cut to size. Then said blank may be drop-forged, pressed, orotherwise formed to shape the 1101- low brace w integral with the metalsimultaneously with the bending or shaping of the. other parts.

In Figs. 1 and 6 provision is shown for an additional bolt, J, throughthe two parts of the chair below the base of the rail, the bolt J beingshown in Fig. 1, and holes j therefor in Figs. 2 and 6. Said bolt,instead of being additional to, maybe substituted for the bolt D,dispensing with the latter, so that either or both of said bolts may beused, as preferred. The lower flanges, f, of these chairs are providedwith holes H, through which the chairs may be spiked or otherwisesecured to the cross-ties of the track.

Having thus fully described my said im' provement, as of my invention Iclaim-- 1. A twopart chair for girder-rails, shaped to lit against andsup port the webs of the same, and provided with lugs, as L, stamped outto support the lower flanges of the rails, substantial] y as and for thepurposes set forth.

2. A two-part chair for girder-rails, provided with lugs for clampingthe flanges of the rails and with hollow side braces, both lugs andbraces formed integral with the metal of the chair, substantially as andfor the purposes set forth.
